Tweetbot is easily the most used app on my iPhone and, with my new iPad arriving in three days, I imagine the same will be said for that device too. Honestly, with streaming and Retina elements, I truly cannot think of a reason for anyone to not at least give Tweetbot a try.

Tweetbot 2.1 for iPhone is available here. Tweetbot 2.1 for iPad is available here.
